STEM WINDING AND SETTING WATCH.

SPECIFICATION forming part of Letters Patent No..380,225, dated March27, 1888.

Application filed December 2, 1887.

To aZZ whom it may concern.-

Be it known that I, OSCAR F, STEDMAN, of Ouyahoga Falls, in the countyof Summit and State of Ohio, have invented certain new and usefulImprovements in Stem Winding and Setting YVatches; and I do herebydeclare the following to be a full, clear, and exact description of theinvention, such as willenable others skilled in the art to which itpertains to make and use it, reference being had to the accompanyingdrawings, which form part of this specification.

My invention relates to an improvement in stem winding and settingwatches; and it con sists in, first, the combination of an endwisemovingwindingstem with the endwise-moving bar, having its inner end beveled,and which is connected with a swinging springactuated cam for thepurpose of moving the vibrating yoke, which carries the intermediatewinding and setting wheels; second, the combination of the vibratingyoke carrying the intermediate winding and setting wheels, a springwhich moves the yoke when left free to moveinto contact with thewinding-wheel, and a spring-actuated swinging plate which moves thevibrating yoke into position for setting the hands; third, thecombination of the endwisemoving winding-stem provided with a collar orstop in order to limitits endwise movement with a sleeve which is placedin the stem of the case, and through which the winding-stem has itsmovement; fourth, the arrangement and combination of parts, which willbe more fully described hereinafter.

The object of my invention is, to provide a stem winding and settingwatch in which both the winding and setting mechanisms are operated byan endwise-moving windingstem, to operate the vibrating yoke by aspring-actuated plate at one end and by a spring at the other, thespring connected to the plate being more powerful than the one which isapplied directly to the yoke, to provide a hand-setting mechanism whichcan be applied to any of the stem-winders of American manufacturewithout any material alteration and at a very slight expense.

taken from the opposite or inner side. Fig. 3 is a similar view to Fig.1, the parts being shown in a different position. Figs. 4 and 5 show amodification, the parts being shown in different positions, and the cambeing formed upon the swinging plate instead of upon the vibrating one.

A represents the watchcase, B the end wisemoving winding-stem, and G thecrown attached to its outer end in the usual manner. Inside of thependant D of the watch-case is fastened, by means of a screw or anyother suitable device, the sleeve E, through which the endwise-movingwinding-stem B moves. Upon the winding-stem is formed the stop or collarF, which, as the winding-stem is drawn outward, strikes against theinner edge of the sleeve E and limits its movement. When thewinding-stem is forced inward, the crown strikes against the end of thesleeve and stem and limits the distance that the winding-stem may beforced inward. Near the inner end of the winding-stem is formed a squareportion which passes through the main winding-pinion G, which is held inposition between the two blocks H on the pillar-plate, and .by the slotin the plateitself. This pinion G meshes with the gear-wheel I, which isplaced upon the same pivot orjournal as the vibrating yoke J. \Vhen thewindingstem is turned in either direction, motion is communicated to themain winding-pinion, and this in turn GQmmunicates the motion to thegear-wheel I and the intermediatewinding and setting wheels in the usualmanner.

The inner end of the winding-stem B has its end slightly beveled, andnear this beveled end is made a groove, L, for the purpose of making aslight connection with the endwisemoving barN,which hasits end beveled,so that when the winding-stem is forced inward and strikes against thisbeveled end the bar will be moved endwise outwardly, as shown in Fig. 2.The inner end of this sliding bar N passes through a groove in the underside of the inner block, H, and the bar is held in position swingingplate Q upon the opposite side of the pillar-plate. This swinging plateQ is pivoted to the pillar-plate at one end, and is operated in onedirection by the endwise-moving bar N and in the opposite direction bythe spring R, which is secured to the pillar'plate at one end.Projecting from the inner side of the swinging plate Q is a stud orprojection, S, which is located near its free end, and which stud actsupon the cam T, formed upon the end of the vibrating yoke J, when thewinding-stein is drawn outward, so as to leave the plate Q free to bemoved by its spring R. \Vhen the winding-stem is forced inward and theendwise-moving bar N is forced outward, the SPlll'lgPltlllt. Q; is movedinto the position shown in Fig. 1, for the-purpose of allowing thevibrating yokeJ to be forced by the spring Uinto position for winding.The spring Uis weaker than the spring 1%, and hence when the windingstemis moved outward the spring t causes the stud or projection S on theswing ing plate Q to overcome the pressure of the spring U, and thusmore the vibrating yoke into position for setting the hands. Just assoon as the vibrating yoke is left free to move by forcing thewinding-stem inward, thespringU instantly forces the vibrating yoke intoposition for winding. When the winding-stem is drawn outward, the spring1 instantly forces the swinging plate Q inward toward the vibratingyoke, and at the same ti me forces the endwisemoving barN into theposition shownin Fig. 8. While the swinging plate is forced inward bythe spring It the stud or projection S catches in the notch in the endof the vibrating yoke at the heel of the cam, so as to lock thevibrating yoke rigidly in position for setting the hands. \Vhen thewinding-stem B is forced inward and the endwise moving bar N has beenforced outward, the end of the bar catches in the groove L in thewindingstem, and thus holds the winding-stem so that it can only bedrawn outward by exerting a pull upon it. This endwise-moving bar servesboth to lock the winding-stem and to operate the swinging plate Q. 13ylocking the winding-stem it can only be drawn outward so as to set thehands by exerting a pull upon it sufficient to displace the end of theendwise-moving bar from the groove.

\Vith the exception of lengthening the vibrating yoke, no materialchange is made in the winding mechanism which is employed in all of theAmerican-made watches. By lengthening this yoke slightly and using theswinging plate, the spring R, and the endwise-moving barand giving thewinding stem an endwise movement, a hand setting and stem-windingmechanism is produced and which is applicable to all of this class ofwatches, and which can be applied with very little trouble and with noincrease of cost over the present construction.

In Figs. 1 and 3 a cam is shown formed upon the end of the vibratingyoke J; but it so desired this cam can as well be formed upon theswinging plate Q, as shown in Figs. 4 and 5. In this case the end of thevibrating yoke is made pointed, as shown, and when the swinging plate isforced inward by the spring R the point of the yoke catches over the endof the swinging plate and the yoke is locked in position for setting thehands.

Having thus described my invention, I claim- 1. The combination of anendwise-moving winding-stem, an endwise-sliding bar which is forcedoutward by the winding-stem when the windingstem is forced inward, aswinging spring-actuated plate which is moved by the endwise-moving barin one direction, the vibrating yoke carrying the intermediate windingand setting wheels, and a spring which is applied to one end of thevibrating yoke, sub stantially as shown.

2. The combination of the endwise-moving winding-stem, theendWise-sliding bar pro vided with a pin or projection, the swingingplate, a spring for operating the plate in one direction, the vibratingyoke, and the spring which is applied to one end of the yoke, the yokebeing locked in position by means of a cam for setting the hands,substantially as described.

3. The combination of the endwise-moving winding-stem provided with agroove, L, in its inner end, the endwise-moving bar N, which has itsinner end so shaped as to be moved by the winding-stem and to engagetherewith, a stud or projection formed upon the outer end of the bar andextending through the slot in the pillar-plate, the pivoted swingingplate provided with a stud or projection near its free end, the springIt, the vibrating yoke carrying the setting and winding wheels andhaving a cam formed upon one end, and a spring, U, substantially as setforth.

et. The combination of the pendant D of the ease and the sleeve E whichis secured therein, with the endwise-moving winding-stem provided with astop, substantially as specified.

In testimony whereofI affix my signaturein presence of two witnesses.
